Abstract

Schema de montaj, conform inventiei, în scopul de a gasi o solutie cu cheltuieli convenabile prin utilizarea multipla a elementelor componente utilizate si de a crea în interesul unei depozitari simplificate si al unei disponibilitati mari, la înlaturarea deranjamentelor si la conectari noi realizeaza un aparat telefonic terminal cu utilizarea universala care poate fi reechipat usor si fara cheltuieli suplimentare la fata locului si fara reducerea valorii de folosire fata de aparatele telefonice terminale speciale, de la linii de abonati cu utilizare simpla la cele cu utilizaresimpla la cele cu utilizare dubla respectiv invers. Inventia are la baza problema de a crea un aparat telefonic terminal care poate fi folosit atît la liniile de abonati cu utilizare simpla cît si la cele cu utilizare dubla.The assembly scheme, according to the invention, in order to find a solution with convenient costs through the multiple use of the component elements used and to create in the interest of a simplified storage and a high availability, at the removal of the faults and at new connections makes a telephone device terminal with universal use that can be easily reconnected and without additional expenses on the spot and without reducing the value of use compared to the special terminal telephones, from the subscriber lines with simple use to those with simple use to those with double use or vice versa. The invention is based on the problem of creating a terminal telephone device that can be used for both single and dual-use subscriber lines.
